[0002] A fixture is an auxiliary tool or device specifically designed to fix, position, or support a workpiece for subsequent processing, measurement, inspection, or other operations. Fixtures are typically made of materials such as metal or plastic and have specific shapes, sizes, and functions. They ensure the workpiece maintains accurate position and stability during production, testing, or assembly. By physically fixing the workpiece to the fixture, they prevent movement or deformation during processing or measurement, providing necessary support and ensuring stability and safety during processing. By quickly and accurately fixing and positioning the workpiece, production cycles are shortened, production efficiency is improved, and the accurate and stable position of the workpiece during processing enhances product quality and reliability. Fixtures are used in the processing of bicycle rear forks.

[0003] The bicycle rear fork is an important component of the bicycle's rear triangle structure. It connects the rear wheel axle and the frame, and has a significant impact on the bicycle's stability and riding performance. During the manufacturing process of the rear fork, it is necessary to perform drilling and machining. The rear fork is then fixed using a fixture. However, the fixture is inconvenient to use during the fixing operation, and the rear fork is prone to shifting during the manufacturing process, affecting the machining accuracy.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a quick mold-changing and fixing fixture for rear forks, comprising a base, a mounting seat on the base, a support plate mounted on the top surface of the mounting seat, an adjustment component on the support plate, a clamping plate mounted on the adjustment component, a rear fork body between the adjustment component and the clamping plate, a round rod on one side of the support plate, and one end of the rear fork body fitting onto the round rod. The adjustment component includes two threaded rods and a screw, both threaded rods being mounted on the support plate, a threaded cylinder being threaded onto the threaded rod, a bearing being mounted on the outer wall of the threaded cylinder, and a ring being mounted on the outer ring of the bearing. The ring is mounted on the clamping plate by a screw, and the clamping plate is attached to the side wall of the rear fork body.

[0007] Furthermore, a first socket is opened on the top surface of the base.

[0008] Furthermore, the first insertion hole has an internal thread that engages with the insertion rod.

[0009] Furthermore, the insertion rod mates with the mounting base.

[0010] Furthermore, a second socket is provided on the mounting base, which fits into the plug rod.

[0011] Furthermore, a slot and a mounting groove are provided on one side of the support plate.

[0012] Furthermore, the slot mates with the clamping plate, and the interior of the slot mates with the rear fork body.

[0013] Furthermore, a threaded rod is installed inside the mounting slot.

[0014] This utility model has the following beneficial effects:

[0015] This utility model features a mounting base on the base, with a clamping plate mounted on the mounting base via an adjustment component. Rotating the threaded cylinder on the threaded rod moves the position of the clamping plate, thereby clamping and positioning the rear fork body. The rear fork body is clamped between the support plate and the clamping plate, used to fix the rear fork body of the bicycle, facilitating users to perform drilling, painting, and other processing on the rear fork body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a quick mold change processing fixture for rear forks, including a base 1, a first insertion hole 2 on the top surface of the base 1, a threaded insertion rod 3 inside the first insertion hole 2, a mounting seat 4 on the base 1, the mounting seat 4 cooperating with the insertion rod 3, a second insertion hole 401 on the mounting seat 4, the second insertion hole 401 cooperating with the insertion rod 3, so as to facilitate the installation of the mounting seat 4 at any position on the top surface of the base 1.

[0024] Mounting base 4 has a support plate 5 mounted on its top surface. An adjustment component 7 is mounted on the support plate 5, and a clamping plate 8 is mounted on the adjustment component 7. A rear fork body 9 is positioned between the adjustment component 7 and the clamping plate 8. A round rod 6 is mounted on one side of the support plate 5, and one end of the rear fork body 9 is fitted onto the round rod 6. A slot 501 and a mounting groove 502 are formed on one side of the support plate 5. A threaded rod 701 is installed inside the mounting groove 502. The slot 501 engages with the clamping plate 8, and the rear fork body 9 is fitted inside the slot 501. The rear fork body 9 is clamped between the support plate 5 and the clamping plate 8 to fix the rear fork body 9 of the bicycle, making it convenient for the user to perform drilling, painting, and other processing processes on the rear fork body 9.
